What is the ruling of the Sharia on consuming medicines, vitamins, and foods that contain gelatin extracted from animals not slaughtered according to Islamic law?

The preponderant opinion is that whatever is extracted from a carcass (maytah) or an animal unlawful to eat, such as a pig, if it is processed and transformed into another substance before being added to medicines, then it becomes pure and permissible to use. However, if it is not processed or not transformed into another substance, it remains in its original state, impure and unlawful to use. If its condition or source is unknown, its permissibility is apparent due due to the widespread nature of the affliction (umoom al-balwa) and the unknown origin, and because most of these substances would have been processed. The Ninth Islamic Medical Fiqh Seminar discussed that additives in food and medicine that originate from impure or unlawful sources become Islamically permissible through transformation (istihalah) or consumption (istihlak).
